Book Description
Detailed data were collected from field and laboratory evaluations to determine whether changes in crude oils affect the physical and chemical properties of asphalt binders over time. The test results indicated that asphalt cement properties produced today have the same range of values as those produced in the 1990s. Asphalts with high-viscosity susceptibility were shown to be associated with pavement distress. Field evaluations showed that asphalts with a viscosity susceptibility value lower than 0.088 will perform well without premature failure. Asphalts containing relatively low asphaltenes, particularly those of softer grade, appeared to have a greater probability of producing mixtures that could lead to pavement distress. Data analyses revealed that a good knowledge of the physical characteristics and chemical composition of asphalts can provide a useful tool for distinguishing between asphalts associated with pavement performance.

Chemical properties of asphalts and their relationship to pavement performance
Chemical Properties of Asphalts and Their Effects on Pavement Performance
Author: Raymond E. Robertson
Publisher:
ISBN:
Category : Asphalt
Languages : en
Pages : 52
Book Description
The purpose of this Circular is to familiarize the asphalt user with the source of asphalt, the variable chemistry of asphalt, why variable performance should be expected when asphalt is used in roadways and what is currently missing from the specification process. Several areas are identified where refinements in the specification process would improve the ability to classify asphalts by their expected performance. This Circular summarizes more than 2,500 pages written during the past 20 years on the effects of fundamental chemistry on the rheological properties of asphalt. This Circular should be especially useful to civil engineering students who intend to work in some highway construction-related business.
